log4j 2使用的坑-log4j 2 多线程漏日志问题

经测试  log4j 2 版本在进行多线程输出时 会丢失打印。不知道是什么问题
@Test

public void test01() throws InterruptedException {

int threadSize = 5;

ExecutorService es = Executors.newFixedThreadPool(threadSize);

for (int i = 0; i < threadSize; i++) {

final int j=i;

es.submit(() -> {

Logger logger = LogManager.getLogger(Log4j2Test.class);

logger.warn("ABC"+j);

System.out.println(j);

 

});

}

es.shutdown();

es.awaitTermination(100, TimeUnit.SECONDS);

}

@Test

public void test02() throws InterruptedException {

int threadSize = 5;

ExecutorService es = Executors.newFixedThreadPool(threadSize);

for (int i = 0; i < threadSize; i++) {

final int j=i;

es.submit(() -> {

org.apache.log4j.Logger logger = org.apache.log4j.LogManager.getLogger(Log4j2Test.class);

logger.warn("ABC"+j);

System.out.println(j);

 

});

}

es.shutdown();

es.awaitTermination(100, TimeUnit.SECONDS);
